Embodiment Construction

[0042] In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0043] If the VR device display adopts a direct-type backlight, by controlling the brightness and switching of the light-emitting diodes in different areas of the direct-type backlight, the effect of improving the contrast of the VR device display can be achieved. However, the manufacturing process difficulty, cost and power consumption of the direct-type backlight prevent the direct-type backlight from being widely used in VR devices.

[0044] Embodiments of the present invention aim at the above problems, and provide a display device and a display method thereof, which can improve the contrast of the display device.

[0045] An embodiment of the present invention provides a display device, such as figure 1 shown, including:

Abstract

The invention provides a display device and a display method thereof, which belong to the technical field of display. Wherein, the display device includes: a side-type backlight stacked in sequence, a first black and white display panel, and a second display panel; the second display panel includes a plurality of display units, and each display unit includes at least one pixel unit, so The pixels of the first black and white display panel are in one-to-one correspondence with the display units of the second display panel, and the orthographic projection of each pixel of the first black and white display panel on the second display panel coincides with the corresponding display unit . Through the technical solution of the invention, the contrast of the display device can be improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device and a display method thereof. Background technique [0002] In order to alleviate the screen window effect of VR (Virtual Reality, virtual display) equipment, the resolution of the display screen of VR equipment is continuously improved, which brings the requirement for the contrast ratio of the VR display screen. However, limited by the alignment accuracy, the display screen of VR equipment The contrast of the screen has always been relatively low, how to improve the contrast of the VR device display is particularly important. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a display device and a display method thereof, which can improve the contrast of the display device. [0004] In order to solve the above technical problems, embodiments of the present invention provide technical solutio...
